When a server in a failover group fails, the Group Manager on each remaining server distributes the failed server's clients to create new sessions among the remaining servers.

When the Group Manager receives a token from a Sun Ray Client for which no server owns an existing session, it redirects the client. This redirection is determined according to the result of a load-sensitive session placement lottery conducted among the servers in the group, based on each server's capacity (number and speed of its CPUs), load, number of sessions, and other factors.
